Prediction of total soluble solids and firmness of carrot based on carrot water content

Abstract

There are many cases in which it is desirable to determine relationships among fruit quality characteristics. For instance, total soluble solids (TSS) and firmness (FIR) are often determined using laborious and/or time consuming laboratory tests, but it may be more suitable and economical to develop a method which uses an easily available characteristics. In this study, two linear regression models for predicting TSS and FIR of Nantes carrot based on carrot water content(WC) were suggested. The statistical results of the study indicated that in order to predict TSS and FIR of carrot based on WC the linear regression models TSS = 34.9 - 0.30 WC with R2 = 0.86 and FIR = - 1665 + 55.5 WC with R2 = 0.84 can be strongly recommended.
